Hi All,
I have a COM application that has a method ProcessMessage which takes a pointer
to BSTR. The definition in IDL is as follows.
methods:
[id(1), helpstring("method ProcessMessage")] BSTR ProcessMessage(BSTR*
Message);
I tried calling the method from python as follows:
msg = comtypes.BSTR("111 Command")
app = comtypes.client.CreateObject("Test1.Application")
app.ProcessMessage(byref(msg))
But i get the following error:
Traceback (most recent call last):
File "C:\test.py", line 8, in <module>
app.ProcessMessage(byref(msg))
File "C:\Python25\Lib\site-packages\comtypes\client\dynamic.py", line 42, in
__call__
return self._obj._comobj.Invoke(self._id, *args)
File "C:\Python25\Lib\site-packages\comtypes\automation.py", line 701, in
Invoke
array[i].value = a
File "C:\Python25\Lib\site-packages\comtypes\automation.py", line 300, in
_set_value
raise TypeError("Cannot put %r in VARIANT" % value)
TypeError: Cannot put <cparam 'P' (00b9ea58)> in VARIANT
What could be the problem?
TIA,
Bejoy
